Wikipedia:Naming conventions (baseball players)

This is the naming conventions guideline for the naming of Wikipedia articles about baseball players, including managers, coaches, umpires and other personalities associated with the sport.

As sports go, baseball has a long, rich and well-documented history, resulting in the creation of several thousand biographical articles for baseball players. To avoid confusion among baseball biographies, and to avoid duplication of articles, a set of article naming standards has been proposed:

General rules
The title of an article for a baseball player should reflect the name they most commonly went by during their career. Informally, the name that appeared on a player's baseball cards should serve as the article's title.

Nicknames should only be used when a player went by their nickname professionally instead of their given first name.

Examples: Babe Ruth – Whitey Ford – Lefty Gomez

Disambiguation
Because of the large number of articles about baseball players, disambiguation is often necessary. In cases where two (or more) ballplayers share the same name, disambiguation is often complex and confusing.

The following steps should be followed to disambiguate baseball player articles:
 * 1) Where disambiguation is necessary between a baseball player and another person unrelated to baseball, then the baseball player be disambiguated (if less notable than the subject of the other article) using "(baseball)" in the article name. Example: Lee Smith (baseball)
 * 2) In situations where two baseball personalities have the same name, but different occupations, disambiguate using the occupation. ''Example: Fred Thomas (baseball manager) and Fred Thomas (third baseman)
 * 3) Where disambiguation is necessary between two (or more) baseball players who play different positions, the position should be added to the article name. Example: Ramón Martínez (pitcher) and Ramón Martínez (infielder)
 * 4) *Note: When two pitchers share the same name, but one was a left-hander and the other was a right-hander, then this may be used to disambiguate. Example: Rich Robertson (left-handed pitcher) and Rich Robertson (right-handed pitcher)
 * 5) *Note: When two players share the same position, but one player also played multiple positions, then list both positions. Example: Tom Williams (pitcher) and Tom Williams (outfielder/pitcher)
 * 6) In situations where there are two (or more) retired baseball personalities, these options also become available:
 * 7) *If their careers did not overlap and both players each predominantly played in a single decade, then use that to differentiate between them. ''Example: Tom Baker (1930s pitcher) and Tom Baker (1960s pitcher)
 * 8) *If they were predominantly associated with different leagues (not including the modern American and National Leagues of Major League Baseball), then the league name can be used to disambiguate. ''Example: Bill Blair (Negro leagues pitcher) and Bill Blair (American Association pitcher)
 * 9) *If they spent the majority of their careers with one team, then the team name may be used. Make sure that Player A did not play for the team used in Player B's article title and vice versa. Use the full name of the team. ''Example: John Fitzgerald (Boston Reds pitcher) and John Fitzgerald (Rochester Broncos pitcher)
 * 10) If all previous steps are still insufficient, then use the players' year of birth. ''Example: Lee King (outfielder, born 1892) and Lee King (outfielder, born 1894)
